Mesh Collar Control

Width

Specifies the width (in current linear units) of the collar surface.

Spans Per Segment

Specifies the number of spans for each segment you defined by clicking extra points on the boundary. The number of segments is equal to the number of points minus 1.

Periodic

If checked, the tool builds a periodic (closed) collar surface.

Control Options

Show Surface Deviation

If checked, min and max locators appear at the points of smallest and largest deviation between the collar and the mesh.

Show Deviation Map

If checked, a color deviation map displays the deviation between the collar and the mesh. A deviation scale (ramp) also appears. This shows you what areas of the mesh have been affected, and by how much.

Deviation Map Settings

These options only appear if Show Deviation Map is checked on.

Auto Ramp

If this option is checked (default), the color scale updates automatically based on a range between zero and the maximum deviation from the last operation.

Ramp Distance

Maximum distance between the mesh and the collar surface shown on the color ramp. Areas on the mesh where the deviation is larger than this value are displayed in a solid color (red or purple). The default is 10.0.

Acceptable Distance

Upper limit for the acceptable deviation between the mesh and the collar surface. Regions of the mesh where the deviation is smaller than this value are colored in green. The default is 1.0.

Where the value of the deviation is between the Acceptable Distance and the Ramp Distance, the mesh displays intermediate colors as shown on the ramp.

Note

The Ramp Distance must be kept larger than the Acceptable Distance.

Absolute Value Ramp

Turn on this option if you are not concerned with the direction of the deviation and simply want to view absolute deviation values.

Use Bands

Turn on this option if you want the ramp to display solid bands of color instead of slowly varying colors.

History

Create History

Turn this option on to save the collar’s construction history for later editing.

You can use Object Edit > Query Edit or the History View window and select the collar to re-enter the tool and modify the option values and input points. However, changing the geometry of the mesh boundary or curve-on-mesh used to build the collar will destroy the collar history.
